## Symbology

No exchange suffix is required to handle Canadian listings.  The extension accepts `.TO` and `.TSX` as well as no suffix.  Additionally, a composite ticker symbol can be entered. For example, `AAPL` trades as a Canadian Depositary Receipt, under the symbol `AAPL:AQN`, on the NEO Exchange. The US listing is also found as `AAPL:US`.  Some US and select European data is available from some functions, like `quote` and `historical`.

Indices all begin with `^`.

## Caching

This extension uses `aiohttp-client-cache` with a SQL backend to cache symbol directories, ETF, and index data. It can be bypassed with the parameter, `use_cache=False`. ETF and index data is gathered from a single JSON file which is updated daily by the exchange. The HTTP request is cached for one day.
